Anyone else having issues? I've had 4 out of 7 fail within 1 month. Different locations, some right out of the box. Less than a 50% success rate is not good at all. Any help here American DJ guys? So far they have been replaced with new units which means their must be some serious manufacturing flaws. Are we getting this worked out?

It is possible there was a bad batch, known to happen every where. Take a look at Nvidia and their mobile 8 series GPUs for example. Tons of failures there because of bad solder joints. As for the unit itself, never personally used one so can't help you there.

Also, what exactly is failing in them? Is it the same part for all units or different parts?
